What is the ruling on the state allocating a car and guards for the head of a department, knowing that this falls under the principle of taking precautions for security considerations?

The fundamental principle regarding public funds is the prohibition of disposing of them unjustly, unless there is a legitimate Islamic interest that necessitates such disposal, while adhering to Islamic regulations, such as avoiding favoritism and extravagance. In such a case, there is no harm.

Accordingly, if there is a legitimate Islamic interest in providing a car for the protection of a specific official, and there is no transgression of Islamic limits in doing so, then there is no harm.
